ABSTRACT:
A conveyor belt for pipe conveyors is indicated which includes overlapping of the conveyor belt at the edges when the belt pipe is formed and which consists of rubber or rubber-like plastic material and a plurality of steel ropes, all being alike, embedded therein as tension carriers and extending in longitudinal direction of the conveyor belt. They all have the same mutual spacing in transverse direction of the conveyor belt and are especially rich in elongation. At the runing side of the conveyor belt a continuous, transversely stiff insert is provided in addition, it extends across the full width of the conveyor belt and comprises steel cords oriented in transverse direction. Another transversely stiff, textile insert is provided in addition at the supporting side of the conveyor belt, yet it is not located in the two edge regions of the conveyor belt which overlap when the belt pipe is formed.
